DIRIGIBLE HEADLIGHT.

Application filed June 1,

To all whom it may concern: I

Be it known that I, MAURICE Hrrz, resid- 'ing at Belfort, France, a-citizen of the The invention relates to means whereby the lamps of automobile vehicles can be deand also vertically.

fiected in accordance with curves of the road,

The invention is illustrated in the accompanying drawing, in which Figs. 1 to 4 show one embodiment thereof, comprising mechanism for imparting'horizontal deflection.

Figs. land 2 are a front view and a side view,.respectively, with parts ofthe mechanism broken away.

Fig. 3 is a vertical section on the line 8-3 of Fig. 4:.

Fig. 4 is a horizontal section on the line l l of Fig. 3.

F igs. 5 and 6 are a'front View and a side view respectively, illustrating a modification, more particularly intended for cars having steering. mechanism of the Ford type. I

Fig. 7 is avertical section of mechanism for vertical deflection of-the lamps, igs. 8 and 9 show details thereof to an enlarged scale. I

Fig. 10 is-a front elevational view of a lamp with means for moving it about'ver- -tl021l and horizontal axes.

Fig. 11 is a diagrammatic side view of the attachment to the steering pillar and to manual controls on the dash board of the vehicle. I

a designates a bronze casing made in two parts connected by bolts a and enclosing a worm gearing with a worm wheel 0 keyed to a spindlecl to the upperend of which is fixed the' usual lamp holder or bracket.

This spindle rests on a ball '6, which separates it from a spidle f fixed inside a tubular downward extension a of the casing, and also fixed to the frame of the car. The shank ofthe worm Z) carries, outside the casing a, a pinion 9, connected by a chain it to a sprocket wheel 11, to the axle j of which is keyed a pinion j. The latter 'meshes with a toothed sector is, pivoted at buckle t.

.tance.

and connected by a rod Z tothesteering mechanism of the car.

The pinions a and j and the sector 70 are mounted on a rod m secured by nuts n.

to two bosses 0 on the tubular part at This rod has. a longitudinal slot, p, which allows of adjusting the position of the axle 1' 1 given tothe wheels for steering purposes is transmitted, by the rod l to the sector/c, which by rocking in one or the other direction produces a correspondingrotation of the wheels 12', g, and consequently of the .worm b, the worm wheel .0 supporting'spindle cZ.

and the lamp In themodificationsho Figs. and 6 the sprocket wheel 2' corresponding to the sprocket wheel i in Fig. 2, has a crank armr.

to which is connected one end of a connecting rod 5, adjustable by'means of a turn- The otherend wof this rod is connected to another crank u on an axle w. The latter is mounted in a sleeve 00 secured tothe car, and to it is fixed one of the members of a universal or Cardan joint 3 whose other member is secured to the lower end of the steering pillar ;orLbar-z.. For this purpose, this part of the universal joint isintegral with a nut y which is screwed on inplace of-the nut. usually provided inthese Any other convenient method may be used 7 'wherebv' rotary movement is transmitted from the member a to the axle w. the same on a smaller scale illustrating also -ond casing enclosing mechanism for that purpose, actuatable by direct manual control or by intermediate mechanism from a dis- This additionaleideflecting mechanism may be used alone or simultaneously with the mechanism for; horizontal deflection.

Means for vertical-deflection are shown in Figs. 7 to 9. The lamp is mounted on a rod 2, which can be rocked ona pivot 3uby Y a toothed sector 4 engaged with a worm 5 on an axle 6. To the latter are fixed two ratchet Wheels 7 and 8, with teeth oppositely directed. "By :pulling a -:chain or cable-9, which: carries a pawl, the wheel 8. :is-irotated 'in the direction of the arrow 10 .(Fig. .9). The lamp .is .then dipped as .indicated by the arrow '11 ig. '7). VVhen'the pull is relaxed a spring 12 restores thepawl-tothe position of rest indicated by broken lines in F ig. 9. By pulling a cable 13 the axle i6 is rotated in the opposite direction.

ln 'case of need, vertical deflection can be effected by turning tlIG'QXlG 6fby means of a key =14 7 V Adisconnectible part '15 of the casing'facilitates access 'to the ratchet wheels.

The casing-has azsocket :16 which its on to *theas'pin'dle (ZQ Figs. l'ito 3') and can be fastened to the :same by any convenient means. 7

Jitwill be understood that the two deflect- :ing devices can also be combined so :as to ii ormua single-lamp :support adjustable in all directions. 7
